Detailing

Provide extra vertical and horizontal reinforcing across the end surfaces of the stem to resist cracking. Single #5 bars, anchored at each end with hooks, 6-in. (+/-) spacing for vertical bars, and horizontal bars spaced with horizontal temperature and shrinkage bars are considered adequate for this purpose for conventional inverted tee cap ends. Do not weld bars together for development of ledge reinforcing. Use anchorage hooks to develop ledge reinforcing.
Provide diagonal #7 bars at 6-in. spacing for 2’-6” at the end of ledge. Place the reinforcing such that it is developed at the point it intersects the crack at the ledge-stem interface. See the
Bridge Detailing Guide
for more information on the bar detail.
Use stirrups with a 12 in. maximum spacing. If torsional resistance is explicitly addressed in the design, ensure the stirrup detailing is consistent with AASHTO requirements.
